Abstract

1523330 Regenerating magnesium oxidecontaining alkylation catalysts GENERAL ELECTRIC CO 21 Nov 1975 [25 Nov 1974] 48005/75 Heading BIE [Also in Division C2] Magnesium oxide-containing catalysts which have been deactivated in a phenolalkylation process are regenerated by burning off the carbonaceous matter in an O 2 -containing atmosphere and then hydrating the catalyst by contact with water or steam. The catalyst may be promoted with a manganese oxide.
